Group subclass

Group types have a subclass of Sequence, Choice, or Unordered.

Property Description
Sequence A partially-ordered or sequenced group of data objects.

Each component of a Sequence group is validated sequentially.

Choice Choice group provides the ability to define a selection from a set of components like a multiple-choice question on a test.

A Choice group is valid when the data matches one of the components of the choice group. Validation of a Choice group is attempted in the order of the components until a single component is validated. If the Choice group has an initiator, the initiator is validated first.

Unordered An Unordered group has one or more components. Unordered group can only have an Implicit format property, with the same syntax options as sequence groups: None or Delimited.
